Anatomy scan questions HELP

So today I go in for my anatomy scan for rainbow baby girl! I’m so excited to see her, but also tons of appointment anxiety since I lost my son. I have a list of a few questions I want to ask... but I always come up with things after so I thought I’d ask if anyone had any questions they suggested I ask today! Here’s what I have

1. Where’s my placenta

2. How does she measure on average

3. Heart defects (family history of aortic stenosis

4. Down syndrome markers?

5. Does she have all her parts. 2 hands, 2 feet, fingers toes etc lol.

Drop anything you thought would be helpful! Thank you
